About one thousands of small size specimens will be irradiated in the High Flux Test Module (HFTM) in a limited volume of 0.5 liter in the International Fusion Materials Irradiation Facility (IFMIF). It is necessary to verify that the experimental data of these small specimens about mechanical characterization can be safely extrapolated to standard specimens data, enabling a sound dimensioning of DEMO reactor. The program of Small Size Test Technique (SSTT) in IFMIF/EVEDA (Engineering Validation and Engineering Design Activity) phase for fatigue, fracture toughness and crack growth measurement is summarized, and recent progress and some analysis of the experiments have performed for small size specimens.
